Patented Aug. 5, 1930 CHARLES V. `MCINTIRE, OF FAIRMONT,

WEST VIRGINIA, ABSIGNOR TO CONSOLIDATION COAL PRODUCTS COMPANY, 0F WILMINGTON, DELAWARE, A CORPORATION Ol DELAWARE APPARATUS FOR CHARGING AND DISCHARGING CABCBONIZING OV'ENS FOR FUEL BRIQUETTES -Application led Iune. 12,

This invention relates to apparatus for carbonizing coal, particularly designed for carbonizing the fuel briquettes described and claimed in m copending application Serial led May 29, ,1926.

In carbonizing fuel briquettes in retorts of the type illustrated in Smith Patent No. 1,409,597 it is the practice to charge the raw briquettes into the hot ovens. In my experience I have found this practice disadvantageous for two reasons: first, when the briquettes come in contact with the hot walls o the ovens the rapid evolution of gas usually causes them to split open, and, second the briquettes next to the walls are coked much more rapidly than those in the interior o the ovens, thus necessitating a long, detrimental soaking heat for the former to etect the de'- sired carbonization of the latter. In accordance with the resent invention I place the briquettes in thin layers upon a perforate support spaced from the walls of the ovens so that they do not come in contact with the vlvalls but are heated uniformly by radiant eat.

For ease in handling I prefer to make the supports for the briquettes in the orm of removable trays and in accordance with the present invention have provided mechanism for moving these trays into the ovens and withdrawing them after carbonization. Associated with this charging and discharging mechanism. I have providaed means for depositing a layer of briquettes upon the trays as they are moved into the ovens and means for dumping the trays and quenching the briquettes after carbonization. The trays are dumped before quenching to conserve their heat. I prefer to employ a retort comprising a bench For this reason I mount my c iarging and discharging mechanism on a vertically movable cage which can be raised and lowered to operate in connection with any one of the vertically disposed ovens.

In the accompanying drawings which illustrate `a preferred embodiment of my invention, Figure 1 is a side view partly 1n section taken along line 1-1 of Figure 2 showing the carbonizing retort and the mechanism for feeding, discharging and quenching; Fig- 1926` Serial No. 115,435.

ure 2 is a View also partly in section taken along line 2-2 of Figure l and Figure 3 is an enlarged transverse sectional detail through one of the ovens taken along line 3-3 of Figure 1; Figure 4 is 4a plan View taken along line 1-1 of Figure 1 and Figures 5, 6 and 7 are transverse sectional detalls taken along lines 5 5, 6--6 and 7-7 ure 4, y In these drawings 1 represents a carbonizing retort comprising a bench of horizontal superposed muiile ovens 2 which are heated from above and below by means of transverse heat fines 3 to which gas and air are fed b conduits 4 and 5 respectively and from whic the products' of combustion are removed through waste heat iiues 6. The briquettes 7 are supported within the oven uY on atrain of coupled trays 8 provided wit perforate bottoms 9 made of some heat-resistant screen cloth. The trays are provided with longitudinal flanges 11 which are received and supported by longitudinal slides or tracks 12 on the side walls of the oven. The briquettes are placed upon the rows deep, and the trays so loaded support the briquettes substantially midway between the floor and roof of the oven. I shall now describe the mechanism by which the'oven's are charged and discharged and the briquettes quenched.

Mounted adjacent the front of the retort is a. tower 13 which carries at its upper end a fixed bin and feed hopper 14 to which raw respectively of Figbriquettes are conveyed from the briquetting presses by means of a belt conveyor 15. one side of the hopper front of the ovens a cage 'guidcways 17 for vertical movement, and raised and lowered by means of a winding drum 18 mounted on the upper frame of the tower, cable 19 and sheaves 20. This cage carries mechanism for moving the trays into and out of the oven, Ameans for feeding briquettes to the trays as they are moved into the oven, and means for quenching the carbonized products.

The cage supports the trays upon tracks 22 provided withdouble flanged guides 23 which receive the flanges 11 on the trays. Likewise trays in thinlayers two- 14 and immediately in l 16 is mounted in t mounted upon this track 22 is @a ram or puller 24 provided with a coupler 25 designed to connect with the rear member of a train ofv l23 of the track 22 are in registry withv the slides 12 of one of the ovens the trays can be moved into and out of that oven by proper manipulation of the winding drum 28.

On itsv oven side and immediatel above the track 22the cage carries a movable feed hopper 31 which receives raw briquettes from the'bin 14. The lower and discharge end of this feedl hopper 31 is closed by means of a shaker plate 32 swin ingly supported by means of four suspensi n arms 33, rlhe side wall of the hopper 31 nearest the oven ter minates a sucient distance above the late to permit the passage of briquettes. A orizontal reciprocation of the shaker plate in the line of travel of the trays is edected by means of a crank 34 driven b means of a worm wheel 35, connecting ro 36 and lever 37 depending from the tray and forming, in eiect, an extension of the suspension arms. As the trays are moved into an oven raw briqiliettes are deposited upon them by means of e shaker feed mechanism just described, the

reciprocating plate causing the raw briquettes to move out of the hopper onto the plate, and thence off its outer end onto the trays passin beneath; After the riquettes have been carbonizcd the trays are withdrawn by means of the ram 24. Both bri uettes and trays are then in a ver highly fore the riquettes can be handled they must be quenched. I shall now describe the means by which l accomplish this.

An intermediate section 38 of the track 22 of a length equal to the train of trays is :discontinuous with the end` sections and is iv- '.otally'mounted at 39 about its longitudinal axis, thus forming a tipple. Immediately below 'this tipple is a bin41 terminating at one side in a water bath 42 and at the other in a discharge hopper 43. Pivotall mounted at 44 upon the lon 'tudinal'divi ing wall 45 between the water ath and the discharge hopper is a basket 46 in the shape of a cylindrical segment, the arcuate side Wall and that portion of the bottom on the water bath side of the pivot-being perforate, While the ends and that portion of the bottom on the discharge ho per side of the pivot are imperforate. T e basket is raised and lowered about the Cpivot by means of cables 47 passing aroun winding drums 48 on a shaft 49 rotated by means of worm set 50. The water bath is rovided with a sluice valve 5l for the remova of dirt or braize.

When a set of trays is to be dum ed the basket is submerged in the water bat as ilimacat Y eated condition and lie-- 38 of the track manually rotated about its` longitudinal axis until it and the traysk asv sume the dotted line position shown in Figure 2, thus discharging the carbonized briquettes into the basket and the water bath.

The trays are retained in the tipple by means of the double ilanges 23 of t e guide.

order to facilitate the return of the tipple to Y its normal position and to retain it in that position during longitudinal movementof the trays, the tippley is provided with two depending counterweights 52. When the tipple has returned to its normal horizontal position the tra s, still in their highly heated and unquenc ed condition, are in readiness for receiving a new charge, and may be returned to the empty oven, first however bcing loaded with briquettes as they pass under the feed hopper 31.

' The quenched bri nettes in the submerged basket are nowv read means of the worm set 50, winding drums 48, and cables 47, the basket is swung into the elevated position illustrated in dotted lines in Figure 2 and the briquettes discharged into the hopper 43, the lowerend of which hopper is normally closed by means orn a swinging counteru'eighted door 53.V From this hopper the briquettes are discharged into a wharf 54 and thence orto a belt'conveyor 55. y

The vertical travel of the cage is `suiicient to permit alignment of the track 22 with the y for discharging. By

tracks 12 of the several ovens. l also preferbin 14 to the hopper 31 when the cage is above the position illustrated in Figure 2, and that carbonized briquettes cannot be discharged from the hopper 43'to the Wharf 54 when the cage is below the position illustrated in Fig-` ure 2. lt is to be understood, ofcourse, that'` the hopper 31 is loaded when inproper relation with hopperV 14 and carries sufficient briquettes to supply all of the ovens at least once. 'lhe same is true of hopper 43 so that the discharge of briquettes from this hopper to the wharf need be eliected only periodical ly'and when the cage is in proper position.'
